ICD-10 Code H27.131 – Posterior dislocation of lens, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.131 – Posterior dislocation of lens, right eye
What it is
This code identifies a lens that has moved backward from its normal position in the right eye. It indicates posterior dislocation or displacement of the crystalline lens, not a cataract diagnosis.
Clinical signs
Findings may include blurred vision, monocular diplopia, or an abnormal lens position on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H27.131 when the record clearly states posterior dislocation of the lens in the right eye. It is appropriate when the provider documents lens displacement into the vitreous or posterior segment, or equivalent wording. Code the right eye only when laterality is explicit.
Do not use for
Do not use this code for cataract, aphakia, or unspecified lens disorder. If the note does not confirm right-eye involvement or posterior dislocation, check documentation.
Coding tip
Verify both laterality and the direction of dislocation before assigning H27.131.
